Add 'fdt print' and 'fdt list' test which works as follows: - Create fuller FDT, map it to sysmem - Print the entire FDT, parts of the FDT and select properties - Compare output from the print or list
The test case can be triggered using: " ./u-boot -Dc 'ut fdt' " To dump the full output from commands used during test, add '-v' flag.
